To (LH (ch/mt it /m/,/ con/cara:

Bo it known that l., PETER Bns'r, of Elizaboth, in tho county of Union and Stato of Now .lorscy, havo invcntcd a ncw and lniprovod 'il`rolloy-laso, of which thc 'following is a full, cloar, and oxact doscription.

y invontion rolatcs to improvcmcnts in trolloy bascs or supports which aro attachcd to tho lops of trollov-cars to support tho polo and trolloy.

Tho objoct of m invcntion is to produco a Vory simplo and compact dovicc which can bo usod in cmmoction with ordinary trollcy polos and cars. which onablos thc polo to bo lot down practically [lat with tho car and turnod around whcn noccssary, which is const ructod in such a way as to turn Vcry oasily, which has a convonicnt mcans for rogulating tho spring tonsion on thc polo, which is also constriu'tod in such a wa)v that whon tho polo is loworod tho tonsion thcroon will bo roducod to almost nothing, and which in gonoral providcs an ofliciont durablc` watertight trllc \'-support in which thc parts arc ]nz'ictic.all \v arrangod and casily acccssiblo.

To thosc onds myinvontion consists of cortain fcaturos of construction and combinations of parts, which will bc horoinaftcr dcscribod and claimcd.

Rcforcncc is to bc had to thc accompanying drawings, forming a part of this specification, in which similar ligurcs of rcfcrcncc indicato corrospoiuling parts in all thc vicws.

Figurc l is a sidc olcvation of my improvcd dovico. Fig. 2 is a rcar clcvation of tho samo. Fig. 3 is a dotail section of thc turrot or cap forming a part of tho invcntion, and Fig. l is a soctional plan on thc linc l -l of Fig. 2.

Tho dcvicc is providcd with a basc portion lt), [n'oforably in tho form of a cylindcr, and in an)v cvont having a cylindric-al intcrior, this baso portion or cup boing also providcd with llangcs ll to thc ond that it may bo oasily attaclual to a car-top. Projccting ccntrall)v upward from tho bottom of tho basc portion or cup lt) is a standard or post l2, which is roducod and scrow-thrcadod at its uppcr ond, as shown at 13, so that thc said portion mav roccivo nuts let, which arc adaptod to faston in placc tlu` cap or turrot l, and tho lattor [its snugly on tho top of tho nut lt) and ovorlaps thc sido odgcs of thc lattor, so as to mako tho said cup wator-tight. 'l`ho cap or tm'rct has a contral hollow dcpcnding guidc l(i, which is adaptcd to it on ovor thc post l2, and tho bottom wall of thc cap or turrct 15 is proforablv inclincd upward and outward from tho contor, as shown at lT, to providc a suitablo bcaring-surfacc for tho rollors prosontfy roforrod to. Tho cap or turrot has also a boro cxtonding upward. from tho hollow guidc l(i to rocoivc tho roduccd ond l of thc post 12, and thc su porstructuro or brackot lS of tho turrot is rcccsscd, as shown at ltl, to providc for gotting at thc nuts l-l. Tho brackct part IS of tho turrot is rcduccd as a mattcr of convcnionco; but it will bo of courso umlorstoml that this is a morol mattor of dosign and that tho oxtorior shapo of any of tlic parts is not very cssontial.

lVithin thc cup or basc portion 10 is a spidcr having a ring 2l, which oncirclcs tho guido 16, and arms 22, on which arc looscly mountcd thc rollcrs 22), which lit thc top and bottom walls of tho chanibcr in tho cup lt), the bottom wall being tho bottom of tho cup and tho top wall bcing thc part 17 of tho turrct or cap 15. Thc spidcr just rcfcrrod to is an important foaturol of tho invcntion, audit will bo soon that it scrvcs pcrfoctly to kocp tho rollors 23 propcrly spacod, so that thcy shall bcar cvonly on tho parts intondcd to run on thom, and thcy arc prcvcntcd from crowding or grinding togothcrsan ohjoction common to bcaring-rollcrs.

Thc turrot has in tho brackot portion IS a. horizontal way 2-l, in which is hold tho slidoblock 25, and this is rocossod longitudinally, as shown at 26, to provido for tho adjustingscrow 27, which oxtcnds longitudinally in tho slidc-block, tho throadod portion litting an up\\'arlly-oxtonding boss 28 on tho brackot 18 and thc scrcw boing liournalcd in tho dcpcnding part 2:L of thc block 25, whilc tho outor ond of tho scrow is profcrably stpiarod, as shown at 2%), so that a, wrcnch can bo con- Vcniontly applied to it. lt will bo scon that by turning tho scrow in or out the slide-block can be similarly moved, and in this way the tension of the springs 31 can be nicely adjusted. These Springs are arranged on opposite sides of the bracket 18 and are attached to studs on opposite sides of the slide-block 25, and the opposite ends of the Springs are attaclied to the upturned lower end of the base 32 of the trolley-pole 33, which base is pivoted, as shown at 34, on the upwardly-extending boss 35 at the top of the bracket 18. Obviously any suitable connection can be made between the part 32 and the ordinary trolley-pole, or the part 32- might be the pole itself. The obj ect of having the boss 35 and the upturned part 32;L of the trolley-pole is to enable the spring 31 to almost center when the pole is tipped flat, as shown by dotted lines in Fig. l, and so the tension on the pole 32 is greatly reduced and the pole can be very easily manipulated when brought down to the position stated. It will be seen that this construction also makes a Very compact arrangement, and to further facilitate this the part 32 is preferably bifiurcated, so that it can shut down over' the part 35. It Will also be noticed that the whole device is extremely compact and water-tight, that the turret portion turns very easily on the roller-bearings, and that for this reason the turret can be easily turned around completely, so that the trolley-pole will extend to either end of the car as desired.

Having thus fully described my invention, Iifclaim as new and desire to secure by Letters Patent- 1 A trolley-base, comprising a hollow base or cup portion having means for attachment to a car, a turret mounted on the hollow base and constructed to carry a trolley-pole, a Vertical guide arranged between the hollow base and the turret, a spider independent of both base and turret, and comprising a ring turning freely on the guide, and radial arms, and bearing-rollers on the arms of the spider the said rollers fitting against the hollow base and the bottom of the turret.

2 In a trolley-base, the combination with the turret and the pole pivoted thereon, of the slide-block movable in and out of the turret7 the said block being hollowed out to form a housing, a nut portion on the turret, and a screw journaled in the slide-block and contained in the hollow thereof, the said screw engaging the nut portion on the turret.
